LIGHTING ATTACHMENT FOR SEWING: IMAOIIINES.

Application filed January 21, 1927.

This invention relates to electric lighting devices for attachment tosewing machines, and has for its object to provide a lighting attachmentwhich is simple in construction, inexpensive to manufacture and ofmaximum utility.

Another object of the invention is to provide an electric lightingattachment which may be readily secured to the gooseneck frame of thesewing machine in the simplest possible manner and without pre-shapingthe gooseneck to receive it.

Another object of the invention is to pro vide a lighting attachmentwhich may be so positioned upon the sewing machine as to produce themaximum of illumination of the work without objectionable reflection orshadows. 7

a further object of the invention is to provide a lighting attachmentwhich will not be subject to excessive or objectionable vibration whenthe sewing machine is in operation.

A. further object of the invention is to provide a lighting attachmentwith a reflector which will not only shield the lamp bulb fromaccidental injury but which may be adjustably positioned to direct therays of light in a plurality of directions, as desired.

A still further object of the invention is to provide the lightingattachment in such posi tion on the machine that it will not interfereor need to be shifted or manipulated by the operator when moving thesewing machme head into the cavity of the usual drop head cabinet, orwhile placing the cover of a portable machine over the sewing machinehead.

Theseand other objects and advantages of the invention will be moreapparent as T proceed with the specification. The invention consists inthe various devices and combinations of devices illustrated, describedand hereinafter more particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a side elevation of a sewingmachine frame, to the front of which my lighting attachment has beenapplied.

Figure 2 is a plan view of a portion of the frame with the lightingattachment applied thereto.

Figure 3 is a side elevation of the lighting attachment and apart of theframe, with the reflector and a portion of its support in verticalsection.

Figures 4,5 and 6 are sectional views, taken Serial No. 16%,506.

through the lamp reflector in the plane indicated by he on Figure 3, butshowing different positions of the reflector.

Figure 7 is a view, in perspective, of the reflector, detached.

Figure 8 is a view in perspective, of the housing support, upon theouter end of which the reflector is mounted.

Figure 9 is a perspective view of a modilication.

Referring to said drawings, it will be seen that the sewing machineframe, commonly known as the gooseneck, comprises a standard a, anoverhanging horizontally disposed arm ii, to the forward end of which issecured the sewing machine head the standard being mounted upon a worktable I) suitably supported upon a cabinet or table indicated at E.

TVithin the gooseneck and head are contained the usual operating sewingmachine parts, which form, per se, no part of the present invention andtherefore need not be described.

The lighting device proper consists of a conventional lamp bulbindicated at 1, inserted in a conventional socket indicated at 2. Thesocket contains the usual switch which may be operated to turn thecurrent on and off, as desired, by manipulating the chain 3. Thelighting device as a whole is secured to the gooseneck by means of abracket support indicated as a whole by the letter F. This supportcomprises a platemember 4:, provided with an integral. body member 5.The bearing face of the plate member 4: will be so shaped as to fitsnugly against and be complemental to the outer surface of the sewingmachine gooseneck. The plate f is provided with suitable aperturesthrough which screws 6 are passed, in order to secure the plate to thegooseneck.

The body member of the support F is interiorly bored as indicated at 7in Figs. 3 and 9, one end of the bore being open to receive the end 8 ofthe lamp socket 2. The end 8 of the socket may be exteriorly screwthreaded to more securely unite the socket 2 to the body member 5. Thisend 8 is centrally apertured to provide a conduit for the feed wires 9in the cable 10, which wires are connected to the switch mechanism inthe socket 2 in a conventional manner. The cable 10 extends through thebore 7 and through a suitable aperture 11 in the wall of the body member5, as clearly shown.

till

Surrounding the socket member 2 is a tubular housing support 12 providedat one end with a cut-away portion or recess 13 to accommodate the pullchain 3. The housing 12, which serves also as a support for thereflector, 16, is provided at its forward. end with an enlarged annularbearing ring 14 terminating in a circular shoulder 15. The reflector 16is shaped so that its end17 will it over the supporting ring 14 of thehousing12, the reflector edge 18 resting against the shoulder 15. Theseparts are made with a nice lit and the frictional contact, whilesu'flicient to hold the reflector 16 in proper position withoutvibration, is such as to be easily overcome by the operator whendesiring either to remove the reflector 16 from the housing 12 or whendesiring to turn it axially about the housing so as to change thedirection of the rays of light from the bulb 1. In other words, thereflector 16 is adjust-ably and removably mounted over the end. 14 ofthe housing support 12.

The end of the reflector 16 is closed and dome shaped as indicated at19. Intermediate the dome end 19 and the supporting end 17,.the body ofthe reflector is cut away as indicated at 20.

In the modification shown in Figure 9, the body member 5 is provided atits open end with a forwardly projecting stud 21, exteriorly screwthreaded to fit within the longitudinally apertured member 22 of thesocket 2. Said member 22 is recessed and exteriorly screw threaded so asto be readily secured to the threaded stud 21. The socket 2 may belocked in position if desired by a set screw 23.

It will be seen that the lighting attachment shown is placed. on thefront of the machine, close to and alongside of the overhanging arm Balso that the lamp is thus permanent- 1y supported, well to one side ofthe needle bar head C; that the rays .of light from the lamp bulb willfall obliquely from the operators right and downwardly to the table ,1),and thus illuminate that edge of the presser foot relative to which theedge of the work is usually guided; and that in this position the.casting of objectionable shadows is en tirely avoided.

It will. also be understood that by placing I the lighting device on thefront of the machine instead of on the rear, ashas heretofore been done,not only are objectionable shadows avoided, but such reflection of thelight as is caused by the rays striking the material or the table D ofthe machine, will be directed rearwardly and away from the operatorrather than forwardly and toward the operator, as occurs when the lampis placed on the rear of the machine.

It will also be understood that by reason of the adjustability of thereflector 16, the operator may cause the rays of light to ex tend invarious directions, as desired. For example, she may wish to have therays of light fall to her lap and, by turning the refleotor about itslongitudinal axis, so that the opening 20 is in proper position, shewill get illumination in any desired position.

Another advantage resulting from the lecating of the lamp on the frontof the machine is the convenience which is thereby a fforded to theoperator to manipulate the switch chain 3.

Again, by placing the lighting device upon the front of the machine, thehorizontal arm may be most conveniently grasped by the operator withouttouching the lighting device, when lowering the mechamsm as a. wholeinto the chamber of the drop cabinet; and similarly, the lighting deviceis quite out of the way of the hands of the operator in the act ofraising the machine from the drop cabinet into operative position; thusaccidental injury to the lamp in the manipulation of the head isentirely avoided.

Another advantage in placing the lighting device on the front of the armlies in the fact that it leaves the back clear for the attachment of amotor and such other devices as may be desirable.

The use of my invention has demonstrated the fallacy of the heretoforeassumed disadvantages of such arrangem.ent,as, for instance, the glareof the light at the front annoying the operator. By the arrangementherein shown and the adjustability of the reflector for the light, Ihave demonstrated that there is no direct glare from the light to theoperator and none from the reflected light upon the work.

In tilting the frame backward to oil the machine parts, as is necessary,the lighting device when positioned in front as shown is not subjectedto damage, as not infrequently occurs when the lamp is secured to therear of the arm.

The dome shaped end of the reflector and the reflector itself protectthe lamp bulb 1 from possible damage when the operator may be using apair of scissors.

Positioning the lighting device upon the front of the arm results in thelamp bulb casting the light in the most effective position upon thematerials and machine parts; and makes the renewal of worn out lampbulbs and replacement of a new bulb more easy of accomplishment.

Moreover, when the operator desires to read an instruction book, studypatterns or make changes in the machine, she is able to quickly andeasily remove the reflector 16 and attend to the necessity of the momentin a natural and relaxed position without the necessity of illuminationother than that given by the bulb with the reflector removed.

It will be understood of course that by firmly securing the bracketsupporting memill teeaeeo ber F by screws 6 or other suitable means tothat part of the arm B subject to the minimum of vibration, the lightingdevice is rendered vibrationless also, and that by directing the opening20 of the reflector away from the operator, the latter will experienceno inconvenience, as the interposed reflector will eflectively preventheat rays from the bulb 1 annoying the operator.
